B 100mm

Use the drop down menu below to select the spigot size required. Spigot size determines height and will therefore determine price. Height will be determined as spigot size + 100mm by default. Use the 'Other info' box if you need to specify a different height. If required you can also switch the spigot to the adjacent face of the box using the 'Spigot location' drop down.

There is also the option to include the 20mm flange at the bottom of the box (not required with diffuser style grilles).
